Very happy to see the Spec# release. Looking forward to giving it a run around this weekend.
I've often wondered how Microsoft measures the return on investment when it comes to things like Channel 9. Should the pointy nosed bean counters ever start pounding on Charles' and the rest of the 9er crew's doors demanding a blood sacrifice then I will happily get on a plane, come to the 'States and explain to them - with diagrams - why Channel 9 rocks and from my perspective represents the best outreach / programming community initiative I've experienced from Microsoft in 15 years of programming on Windows.
That Vista Bridge API is a gift sent from the Gods. This has been frustrating me so much, and finally, a solution. Thanks for the link, guys.

charles, pleeease interview him
Hi Dan,
Thank you for helping out. I am using VS Express 2008. I added the SmartThread dll (v 1.0) and since I don't have (or want) an iTune library, I commented out its references. InnerTube seems to compile fine. I can launch it and it looks I can add feeds as needed, but when I click on refresh feeds the apps stops working (I get the Windows message "InnerTube has stopped working") and it exits. I could probably try debugging it, but my debugging skills are very basics.
Edit: i tried debugging and the code stops on file InnerTubeService.cs at line 202:
XmlTextReader xr = new XmlTextReader(wc.OpenRead(youTubeUrl));
The debugger says:
System.Net.WebException was unhandled by user code
Message="The remote server returned an error: (400) Bad Request."
Source="System"

Thanks for your help
Thanks giovanni, this is very helpful, it looks like the URL for the feeds that are added aren't XML files, hence the bad request. I suspect it's a bug where, if your using a username to add a feed, YouTube needs to encode that username in a particular way to display it correctly.
To help understand the issue, can you copy and paste your InnerTube.xml file which you can find at $username$\Videos\InnerTube\InnerTube.xml (on XP at Documents and Settings\$username$\Videos\InnerTube\InnerTube.xml) . The InnerTube.xml file will have the URLs that the code above is tryign to call and we can figure out why one of them is bad.
Thanks!

<?xml version="1.0" encoding="utf-8" ?>
It looks like I have a bug in the code that builds the FeedUrl for custom searches. The easy way to fix this is to
As you can see, I've changed the "vq=" to "?q=" which is a well-formatted XML result.
Apologies for that, but thanks for finding the bug! Let me know if you can't get it to work
In which case, is there any chance that text layout could be fixed because it seems (at least to me, maybe someone knows better), that text layout is completely crippled in Silverlight 2.
When I saw that you only have Textblock but no FlowDocument and FlowDocumentPageViewer class in Silverlight 2, I figured that's OK, they don't want to bloat the download so they left it to the app developer to provide their own classes for doing layout that more complex than TextBlock can manage. Except you can't because there's no way to measure text. In particular the FormattedText class is absent from Silverlight. You can do some basic measurement by putting text one word at a time into a TextBlock object and reading back the ActualHeight/ActualWidth properties, but that doesn't help you much because you don't have other information needed for vertical layout such as the baseline. Important metrics are also missing from the FontFamily class.
Kindof sucks that a really important core class like FormattedText got left out when there are controls like DataGrid in the main install that could have been provided as a separate assembly for the few people that will use that instead of their own or a 3rd party control.
